STOCKHOLM August 25(Reuters) - Sweden's center-left opposition parties - the Social Democrats, Green and Left parties - hold a solid lead ahead of next month's election but it has narrowed over the last month to 48.8 percent of votes if the election were held now, an opinion poll showed on Monday.
The Novus poll of polls for Swedish radio showed support for the opposition down 0.9 percentage from the previous survey at the end of June, while backing for the incumbent government rose by 0.7 percentage points.
Support for Prime Minister Fredrik Reinfeldt's minority, center-right Alliance government was at 37.6 percent in the poll.
The current government is made up of the Moderates, Centre, Christian Democrat and Liberal parties.
The Sweden Democrats would win 10 percent of votes, according to the poll, while other small parties and undecided voters accounted for the remaining votes.
The election is scheduled for Sept. 14.
